[evlatests] Tests 12/20/05

[Tom Frost]

from what I read here, it sounds reasonable that it is indeed some
type of file conversion problem, as both Operators report that the 
antennas "parked" when commanded to do so....I'm assuming of course,
that the 'park' command uses different software from that used while
Observing....if not so, either Ken or Pat can set me straight...at
this time I don't think it is a problem with either the ACU or MIB as
the 'park' command would come to these modules I believe...
